SPINDLE SUPPORTING AND DRIVING DEVICE FOR SPINNING-FRAMES.

SPECIFICATION forming part of Letters Patent No. 445,500, dated January 2'7, 1891.

Application filed June 11, 1890. Serial No. 365,065. (No model.)

To all whom, it may concern:

Be it known that I, JOSEPH DUFFY, of Paterson, in the county of Passaic and State of New Jersey, have invented a new and useful Improvement in Spindle Supporting and Driving Devices for Spinning-Frames, of

which the following is a full, clear, and exact description.

My invention relates to improvements in oscillating bolsters for carrying the spindles of spinning-frames; and the object of my invention is to produce a bolster by means of which the spindles. may be held so that they may be conveniently operated by a belt traveling across the frame of the machine, and also to provide means for maintaining a uniform tension on the bolsters and spindles; and to this end my invention consists in certain features of construction and combination of parts, which will be hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in both figures.

Figure 1 is a broken plan view showing the manner in which the bolster and the spindles mounted therein are located with reference to the belt; and Fig. 2 is a broken vertical view, partly in section, showing the construction of the bolster, the manner in which it is mounted, and the manner in which the spindles are mounted therein.

The spindles A are of the usual construction, and are mounted vertically in the arms B of the bolster B, said spindles having a projecting lower end A mounted in suitable hearings in the arms, and having the extreme lower ends formed into pivots a, adapted to rest in corresponding sockets in the bolsterarms. The bolster B has a horizontal body portion, to the outer ends of which are fixed the vertical arms B, which carry the spindles A, as described, and the bolster has fixed to its under side a depending trunnion B which turns in suitable bearings O in the rail 0 of the spinning-frame. The arms B of the frame have an enlarged recess 1), which serves as an oil-conductor to the foot of the spindle, a portion 7) near the top adapted to serve as a bearing for the spindle, and a socket b beneath the recess 1), adapted to receive the pivot a at the foot of the spindle. The trunnion B of the bolster has a depending portion B projecting through the frame and provided with a suitable nut Zr, and mounted upon said projecting portion is a spiral spring D, one end of which presses against the nut and the other against a washer c at the lower end of the bearing C. The spring will thus give thenecessary tension to the bolster. A suitable washer (1, preferably of felt, is placed between the upper end of the bearing O and the body of the bolster.

Upon the upper side of the bolster is a boss 13*, having a suitable cover B and having a vertical bore 1) therein, said bore opening into the horizontal bore b which extends across the body of the bolster and enters the recesses l) in the arms B. It will thus be seen that by removing the cover B oil may be poured in the bore 11 and will flow through the bore if to the recesses b, and thus lubricate the lower bearings of the spindles. The

. portions laterally-extendi ng flanges E", adapted to support a belt. The belt F, by which the whirls and spindles are rotated, extends over suitable horizontal] y'rotating pulleys H, power being taken from a convenient shaft. The spindles are arranged in the frame in relation to the belt F so that the belt will press firmly against the whirls E, so that as the belt is moved the motion will be transmitted to the whirls and thence to the spindles. It will be seen that as the tension of the belt tends to press one whirl out and the trunnion B being oscillated the opposite whirl 011 the bolster will be moved inward, so that there will be an even pressure upon both whirls of a bolster, thereby imparting the same speed to each spindle, and consequently the same twist to the yarns, and as the various bolsters have each the same relation to the belt all are driven at the same speed, thereby imparting an even twist to all the yarns spun.

. In running the spindles from continuous belts instead of separate bands it has been the practice to have a pulley H for every four spindles, there being two spindles on opposite sides of the pulley; but by means of my invention it Will be seen that the capacity of each pulley is doubled, as each pulley drives eight spindles, the oscillating'bolster causing the two spindles it carries to bear with an even pressure upon the belt, as described.

I do not confine myself to the particular construction of the bolster, asit may be made in as many parts as desired,and its construction may be varied to suit the taste of the maker.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. The combination with the frame of a spinning-machine and with a horizontallymoving belt arranged across the frame, of an oscillating bolster having a suitable trunnion mounted in a bearing in the frame, said trunnion having a downwardly-projecting end carrying a suitable tension-spring and vertical arms fixed to opposite sides of the bolster, and spindles mounted in said arms, said spindles having suitable whirls attached thereto adapted to press against the belt, substantially as described.

2. The combination, With the frame of a spinning-machine and an endless belt moving horizontally across the frame, of an oscillating bolster pivoted in the frame, said A bolster for spinning-frames, consisting of a body having arms provided with bearings for the spindles, a central pivot, and oilpassages extending through the body to the arm-bearings, substantially as described.

4. A bolster for spinning'frames, consisting of a body having arms provided with bearings for the spindles, and a central trunnion having a reduced end provided With a nut to 5 retain a spring, substantially as described. JOSEPH DUFFY. lVitnesses: v
